AI Technical Summary

Technical Problem

Current vehicle software architecture is based on distributed ECU design, which has problems such as distributed computing power, limited communication bandwidth and strong coupling between software and hardware. It is difficult to support the needs of high-level autonomous driving and continuous OTA upgrades. Traditional software architecture has bottlenecks in resource scheduling, function iteration and security isolation.

Method used

The system adopts a vehicle-side software architecture, deployed on the regional controller, including a cross-domain service layer, an enhanced service layer, an atomic service layer, a device abstraction layer, and an electronic control layer. This achieves centralized computing power and service decoupling. By combining the communication between these layers, group communication is achieved, enabling communication between the service layer, the enhanced service layer, the atomic service layer, the device abstraction layer, and the electronic control layer.

Benefits of technology

It has improved the overall vehicle intelligence level and development efficiency, increased software reusability, reduced development complexity, enhanced the accuracy and efficiency of vehicle component control, improved the efficiency and scalability of application scenario changes, and improved the user experience.

Abstract

The invention relates to a vehicle end software architecture, an electronic and electrical architecture of a vehicle and the vehicle, and relates to the technical field of vehicles. The vehicle end software architecture comprises a cross-domain service layer, an enhanced service layer, an atomic service layer, an equipment abstraction layer and an electronic control layer communicating with the enhanced service layer which are deployed in a vehicle area controller and communicate in sequence; the cross-domain service layer is used for communication between the regional controller and other vehicle-mounted domain controllers; the enhanced service layer performs logic judgment on the control request signal group and transmits a target control signal to the cross-domain service layer and the atomic service layer; the atomic service layer calls the equipment abstraction layer to control the corresponding vehicle component to execute a control function based on a target component control service pointed by the target control signal; the equipment abstraction layer provides standard abstraction of a hardware interface and realizes communication between the component and the atomic service layer; the electronic control layer provides a standard interface of a communication protocol interface to realize communication between the component and the enhanced service layer; and the intelligent level and the development efficiency of the whole vehicle can be improved.
